OBJECTIVE: To investigate the correlation between the polymorphisms of(brain derived neurotrophic factor, BDNF)BDNF gene rs11030104 and rs2030324 and executive function in children with attention deficit hyperactivity disorder(ADHD). METHODS: A total of 206 ADHD children and 212 control children were enrolled in the study. Five mL peripheral venous blood was extracted from each subject and genomic DNA was extracted. The genotypes of rs11030104 and rs2030324 loci were genotyped by PCR/sequencing. The selection was tested by Wisconsin Classification Card Test, Stroop Color-Word Task, Reaction/Nonresponse Task and Stop Signal Task. RESULTS: The distribution of rs2030324 locus gene frequency was different between ADHD group and control group. G allele was the risk factor of ADHD(χ~2=4. 481, P=0. 034; OR=1. 520, 95%CI 1. 031-2. 243); rs11030101 locus gene frequency distribution and genotype distribution had statistical significance between the two groups, and A allele was related to ADHD susceptibility(OR=1. 601, 95%CI 1. 052-2. 436). The error interference score of Stroop test in ADHD group was higher than that in control group(P<0. 05), but there was no significant difference in response time interference score between the two groups(P>0. 05). The SCWT scores of different genotypes of BDNF rs2030324 in ADHD group were different. Compared with AA type and AG type, the SCWT error interference scores of GG type ADHD patients were higher. There was no significant difference among rs...
